AWS cli documentation change

Service: cli · 2026-02-10 · Documentation low

File: cli/latest/reference/ec2/describe-instances.md

Summary

Updated AWS CLI version reference, modified instance tags documentation link, and added comprehensive documentation for SecondaryInterfaces feature

Security assessment

The metadata tags link update improves documentation clarity but doesn't address security. The SecondaryInterfaces addition documents new networking capabilities without security-specific features. Includes standard network security field (SourceDestCheck) but this is existing functionality.
